"Resolution is even worse than Pathfinder 1997 first panorama! :-("

No, it's better.  The original is much better.  We don't have that yet, but we will.  Meanwhile, reflect on the work that went into creating the miserable version of the pan you have before you now.  (Merry Christmas!)

Thanks for this. Can you tell us how it was created from what the Chinese have made available?

I'm sure it is. As it is the descent video, shot at 1024x1024 pixel (while the "HD" video on youtube has just a bunch of pixels). But it has not yet been released... and it does not look like it will ever be. :-( Not until Chang'e 4 at least. :-(

Looks lovely, but I have to say it's really beginning to make me crazy that the "release" is a video camera panning around a television monitor.

Doesn't surprise me in the least.
It as it is nigh on impossible to get any stills, never mind hi res images about the Chinese space programe. Never seen a single image of Tiangong (apart from TV) in orbit for instance.

It's almost as though they aren't entirely comfortable with freedom of information, for some reason. How different, how very different is the information policy of our own dear NASA!

They have different processes for publishing the data, slower than some NASA missions but not unheard of. They do publish the data, carefully and meticulously.
Maybe they ALSO have a bunch of important PhDs with first dibs to get their papers published ?

t = ton

Shouldn't that be "t = tonne"

Not if Jason1701 means 2000 pounds in US Customary Units or 2,240 pounds in Imperial Units.

If Jason1701 means 1000 kg, then it should be tonne.

Life would be easier if my fellow Americans let go of tradition and switched to the metric system.

Yutu is on the move again! On December 21 she made 21 meters from the B waypoint through C to D, probably resting to the south of the lander.

Seems like framegrab from the video in here

There is also a top view of the landing area and presumably the rovers traverse

What I don't understand is: once they've sent data to national TV which also airs over internet, what else do they need to wait to release raw data?!?

From Youtube above but it's probably the same news item.

It doesnt look like CCTV / CNTV are getting any "data" apart from carefully prepared video at this point, hence everything that gets posted anywhere are blurry video frame grabs like these

http://news.cntv.cn/2013/12/21/PHOA1387590503017494.shtml#g=1

These clips are just plain video frame stills from the video they used in this report

Obviously for the same reason you're not satisfied with the TV grab, and are craving the raw images.
I wouldn't be surprised if some science communication / media organisation in China had access to the high-res versions first - (for a yet-to-be-aired documentary perhaps?) similar to proprietary access periods for scientific data. After all, Mars One's basing their business plan on that. Maybe China wanted to do a pilot with Chang'E 3?

Anyway..let's stop whining over this.. please?

From the look of it, CNSA didn't release any data to CCTV, instead, the later had the access to CNSA control room and reported what they saw on the big screen, obviously with the consent from CNSA.

Not much whining to be fair. You should see some of the SLS (exploration plan - frustration with it) threads....as much as we moderate via the true meaning of moderation.

We will keep it calm on all threads, per the forum rules.

Not whining, cobber. No huhu.  Just saying that China is slow to share original data compared to NASA and ESA.

I think this is quite understandable. They are still building up experience, they are not a democracy, they have to learn how to manage public outreach.

Scientists there are subject to scrutiny from the politicians and a single error may have quite strong impact on careers and funding. They have to learn step by step what you can do and when. They have had pretty big failures in the past and they may be scared by the possibility of a sudden failure live or of a misleading information given to the public.

Actually I'm amazed by seeing this coverage for this mission. Respect to the past it looks to me quite an improvement. Derivative matters, not absolute value.

Finally, I think we have two photos not taken from the projection screen.

Nice!

One Q springs to mind - is the rover able to operate independently, out of visual range from the lander?

Two more interesting photos:

The lander one was captioned 'the first hot-fire test of chang'e 3 lander'.
